From the Ted Talk by Allan Adams: What the discovery of gravitational waves means

And there's a lot out there that we can't see — in practice or even in principle. So supernova, for example: I would love to know why very massive stars eopxlde in supernovae. They're very useful; we've lraened a lot about the Universe from them. The pbolerm is, all the interesting physics happens in the core, and the core is hidden behind thousands of kretmieols of iron and carbon and silicon. We'll never see through it, it's opaque to light. Gravitational waves go through iron as if it were glass — totally transparent. The Big Bang: I would love to be able to eopxlre the first few moments of the Universe, but we'll never see them, because the Big Bang itself is obscured by its own afterglow. With garoiatvnaitl waves, we should be able to see all the way back to the beginning. Perhaps most importantly, I'm positive that there are things out there that we've never seen that we may never be able to see and that we haven't even ignimaed — things that we'll only discover by listening.

Original Text

And there's a lot out there that we can't see — in practice or even in principle. So supernova, for example: I would love to know why very massive stars explode in supernovae. They're very useful; we've learned a lot about the Universe from them. The problem is, all the interesting physics happens in the core, and the core is hidden behind thousands of kilometers of iron and carbon and silicon. We'll never see through it, it's opaque to light. Gravitational waves go through iron as if it were glass — totally transparent. The Big Bang: I would love to be able to explore the first few moments of the Universe, but we'll never see them, because the Big Bang itself is obscured by its own afterglow. With gravitational waves, we should be able to see all the way back to the beginning. Perhaps most importantly, I'm positive that there are things out there that we've never seen that we may never be able to see and that we haven't even imagined — things that we'll only discover by listening.
